PS--if there are other vm's still launched and running from the time when the
datastore used to be part of
a cluster, could that confuse anything? Do I have to restart oned to clear
anything up?

Subject: RE: [one-users] clusters in 4.8
OK here we go:
VM in question is taking an image from image store 102 (currently in no
cluster),
vnet 0 "routable private" from cluster 100 "cloud worker"
also a number of hosts, including hosts # 0 and 2, also part of cluster "cloud
worker"
VM stays pending for ever, hold reason is below.--it is requiring that cluster
ID has to be 100.
Same image and same datastore and same vnet outside of the cluster, work just
fine.
Seems like if I require any resource from the cluster, in this case a vnet,
then all resources
have to be in the cluster. Am I missing something?

Subject: Re: [one-users] clusters in 4.8
Yes, you can do:
Cluster A: Host_A0, Host_A1... + VNET_A0, VNET_A1...
Cluster B: HostB0, HostB1... + VNET_B0, VNET_B1...
Cluster Default: DS, DS_System
Then a VM that uses VNET_A0 + DS would be scheduled to Cluster A. Note
that using VNET_A0 constrain resources from Cluster A + Cluster
Default.
Cheers
